Sound stuttering Probook 4535s

Hello, as a HP longtime fan, I bought HP Probook 4535s (LG856EA#ABU) 2 weeks ago. With Windows 7 Pro 64bit SP1.
At first I think that audio sounds was perfect, but after few update packages, which came with HP Support Assistant I think, my sound started to stutter (it feels like computer freezes for 0.5 -1 seconds). It started with youtube.com videos, i thought it was because of Adobe flash. After that sound started to stutter even in Media Player, VLC player and few games which i tried.
Is it hardware or software problem? Do i need to change my computer? It is disappointing to buy business notebook with such a glitch after few days of use.
best regards

Hi,
The stuttering sound problem seems to be related to the new power assistant software either uninstall it or uninstall it and install an old version

Sound stutters in Firefox flash applications over time

If firefox is left open too long, flash sound stutters (each second of the sound will play about 5+ times before playing the next).
While the problem is happening in Firefox, I can open other browsers to the exact same web page and all is fine.
A Hotfix for the problem: in Firefox go to Tools -> Addons and disable flash. Once it's disabled, re-enable it and refresh the page. Everything is back to normal and you don't have restart firefox.
This would seem to point to Shockwave Flash being the problem.
Firefox 3.5.8 Adobe Flash 10,0,45,2 Using the Ubuntu Linux Operating System
I have been looking for 3 weeks now and have not found a solution. It looks like the same problem happens in Windoz, etc.
Help!

Since Firefox is on 3.6.2 (and I assume that's for Linux as well, but I haven't updated my Ubuntu in a month or so) why use 3.5?
You said, "I can open other browsers to the exact same web page and all is fine."
Since they all use the same Shockwave/Flash engine, that would indicate that the problem is NOT in the Shockwave/Flash engine, but rather in the one browser with the issues... namely the outdated Firefox.

Same Sound Stuttering Problem as 50000 other people

http://h30434.www3.hp.com/t5/Notebook-PC-Sound-and-Audio/8560w-sound-stuttering-when-playing-music/m...
and dozens more threads like this
And still no fix. This is ridiculous. I have tried everything, changing to high performance, updating drivers, leaving computer unplugged, turning off HDD protection. Nothing works. This is insane, I work a lot with music how am I supposed to do so when I can't even function on my computer? I think all of us with a problem should just organize into one thread and send a petition or large letter to something. In the mean time, has any one person come up with any other solutions that acould potentially work? Thanks.

See if this is applicable to your situation...
If you have the HP Power Assistant/Power Manager installed, uninstall it and either live without (I don't see the real value in this program as W7 has plenty of power settings you can modify), or install an earlier version of the software.

Sound stuttering on Virtual PC (xp)

I need to use a windows music production app on virtual pc but after installing windows xp, the sound stutters almost like its a system resources problem. I've followed all the tips to minimize cpu load etc, like disabling animation features in windows but its still stuttering. I would have thought my spec would be ok for this but it even happens on the welcome noise. Is this a resources problem or can i change a setting somewhere? Also does anyone know of another virtual host that would work better for sound? I'm not on an intel mac so don't think i can use parallels. thanks guys, Dren.

Hi drennam;
My suggestion is to use a music production application that is native to OS X instead of the one that requires XP. Any attempt to use Virtual PC for anything as resounce intensive as a musical production application is doomed to failure in my opinion.
I am not sure what you are doing but I have found GarageBand to be a very adequete solution on OS X for music production.

Sound stuttering in Leopard on Dual G5 Powermac

I've searched other posts, but haven't seen a related topic, so wanted to air this.
Took a day and a half to load Leopard, as the upgrade didn't work smoothly on my RAID1 10.4 startup disk. It kept breaking the mirror, then wouldn't present the other slice when booting. Eventually I had to move all the data to a third drive then re-init the startup mirror and copy it back. What a pain.
THEN, I notice my old favorite problem is back. I can't make the G5 disable 'nap mode', whenever nap mode is on I get an annoying chirping sound continuously out of the speakers. I had a line "hwprefs cpu_nap=false" (or something like that) previously that disabled this on bootup. I notice the reinstall of xcode 3.0 appears to have removed this, also loading the latest CHUD does NOT provide a tool to turn this mode off. Help!
As if this isn't bad enough, when playing back a video via QT or DVD player, the sound stutters continously a couple of times a second. This isn't something I can live with. If this can't get fixed, I'll go back to Tiger and get my money back.
I have this installed on my Powermac G5 dual 2.0GHz system. I've no intention of loading this on my Macbook Pro until this is fixed.
I tried repairing disk permissions on the startup volume, but beyond that I'm not sure where to look. Any ideas?
Thanks, Dave.

Spoke too soon. I've just noticed has disappeared completely partly through viewing one movie.

When I stream music from my MacBook to speakers via airport sound stutters on and off. When I do so from iPhone all is fine. Can't seem to find any settings to change Tried to shut off firewall but settings will not let me. All software up to date.

2. not that I know of
been looking for something a bit like it got an old ipod thouch in a audio dock in the kitchen and want to give it access to all my music not just play what is synced
so far my only options is to get an app to use upnp to get the music directly from my nas
or get some app which require the computer to be running and running some program to handle it
and as far as I can tell getting access to stuff synced on the atv is a no go

Intel hda, sound stutters in games.

I have yet another problem. Whenever I play games, the sound stutters very badly. I'm using alsa and pretty much everything else works. No problems in mplayer/vlc. Just in games.
My guess is that heavy load causes the problem. I have no clue how to fix it though. Been searching around on forums for a while, but haven't found any solution.
Maybe worth mentioning that the games run just fine. No choppiness at all or other problems.

weird. xmms sometimes stutter(actually stops) for me but that's about it. but i'm not using kernel26 i'm using the -ck kernel which is supposed to be better with these things.
i have an ac97 onboard audio. what sound(-solution) do you have?
it *could* be that your running esd and arts in the background though which _might_ make the sound stutter.
disable esd in a startup manager/script/dir like 'esdctl off' and remove arts.
OT: Is gnome 2.18 compiled now without esd or is it possible to compile gnome without it now?

NGTX560 Single Fan Edition, freezing and sound stuttering problems

I've recently just built a new computer,
CPU- i5 2500k,
Motherboard- Gigabyte Z68M-D2H,
Ram- G.Skill Ripjaws 1600mhz 8gb(4X2kit),
PSU- Coolermaster Extreme plus 700W 52A single rail,
GPU- NGTX560 single fan edition, no overclocks whatsoever on anything.
Storage- Seagate 500gb HDD 7200Rpm Sata
OS- Windows 7 64Bit edition.
Display- Monitor is a LG IPS235, 23.5', if it even matters
When I try to play games it starts to lag, and freeze while causing sound stuttering and then completely freezes the whole computer forcing me to reboot the system. Using the 285.62 drivers.
Games for example include Starcraft 2, which when I open used to freeze straight on the loading screen forcing an immediate reboot. I allowed it through my firewall and now I get past the loading screen and can log in, but straight after I log in, sound stuttering occurs and then the whole computer freezes forcing me to reboot. Another game as an example is Killing Floor, I never got past the "Tripwire interactive" loading screen, looked on google for some fixes, after modifying some .ini files for Killing Floor I was able to get into the menu's, went to options and clicked on display to change some of the graphics settings, extreme rips in the image occured, sound stuttering and frozen on the spot. Retried again but this time didn't touch any settings at all, joined a match, the game loaded but as soon as I entered it froze forcing me to reboot. Need help please thanks
Edit: just tried Starcraft 2, made a custom match vs a bot, got into the game for 20 seconds, started mining minerals then it froze again, this time I can hear the audio still playing perfectly while the image is frozen, mouse can move around, keyboard still works. rebooted after observing these features

Two week old DV6, Sound Stutters Please Help

Purchased a DV6 a few weeks ago and the sound stutters, anyone else having this problem?
Is there a fix or should I send it to HP?
Any help or suggestions would be appreciated.
Thanks

Hi
Can you provide the specific model / product number, dv6 is a series and doesn't give us much information to work with.
Is the stuttering affected by what sound is being played (i.e. game sounds vs a CD or an MP3 file)? Is it just with external speakers or do you hear the same thing in headphones?
Although I am an HP Employee, I am speaking for myself and not for HP.

Hp probook 4535s 16 GB support

Hi
I bought today HP probook 4535 with the following configuration
AMD quad core A6
16 GB of RAM (upgraded from standard 4)
Ati Radeon
750 GB Sata
Guy from customer support says that this PC in his tech. specifications has support for 16GB but he isn't sure if system will be stable. My question if someone here works for HP or knows information I'm looking for to be polite and tells me if this notebook can support 16GB of RAM. I need alot of RAM for my work and I want to be mobile.
Thanks for reading
This question was solved.
View Solution.

Then I am in doubt too as the specs from only 2 months ago state max is 8 GB.
Edit: Hopefully it will work then.
I have found other HP pc's where the specs stated max memory was less than supported by the chipset and installing the chipset max worked.
I have an Elitebook 6910p. Chipset is Mobile Intel 965. Chipset supports 8 GB (2 x 4 GB) of PC2-5300 memory.
HP specs state max is 4 GB ( 2 x 2 GB).
I installed 2 x 4GB of PC2-6400 and it works just great with 8 GB. Memory downclocked to 667 Mhz.
So, maybe you are in luck too.
Please post back and let us know if 16 GB works.

The sound stutters and everything freezes

there's something wrong with the sound on my computer, if i spend 30mins watching a video, the sound stutters annoyingly and my laptop hangs, i always have to restart it, some times this doesn't solve the problem.
It also happens when i'm on skype.... its a dv3 and i updated the driver recently, still no result. is it the sound card???
PLEASE HELP

2nd that. Try running it earlier in the day when things are OK and again immediately after you have a problem (but remember to stop the video on demand first as this will affect the result). Copy and paste both sets of results.

XPS 8700, Sound stuttering during playback

I have a new 2 month old Dell XPS 8700. I notice the other day a sound problem that is strange to say the least. When I play back a .flac or .mp3 file, the sound stutters. It's like it comes out in pulses once a second. It's quite un-listenable. Not sure when this started. I'm running Windows 8.1 fully updated as of 2/6/2015. The problem shows up with Windows 8 music player, Windows Media Player, Windows Media Center and vlc. All show the exact same playback anomaly. It also happens when I use the same players to play an .avi or .mkv video. The sound is bad no matter which audio port I use. I also get the same artifact using USB Headphones with their own DAC. What is weird about this symptom is that if stream Pandora, Somafm, or watch a youtube video, I do NOT get this symptom. The audio is perfectly fine. I ran the Dell PC Checkup and no problems are detected. Device Manager says all my drivers are up to date. Any ideas about what is going on and how to fix this?
Thanks in advance.

I did. I tried the update, but it failed because I already had the update. I had installed it a few weeks ago when I was setting up the PC and downloading all the Windows, Office and Dell updates.
Ironies of ironies is that the failed update helped me resolve the problem. I thought I would uninstall the Realtek drivers via Device Manager which I did. But, before running the update again, I checked to see if the symptom was still present. The stuttering went away! Problem solved.
It seems that this is working with an Invidia sound driver from what I can surmise from Device Manager. So, I'm just not going to install the Realtek driver unless there is a change in the symptom. I'm beginning to think that it was the updating I did a few weeks ago that broke my sound!
Thanks again for helping.

ProBook 4535s has bad keyboard

HP Switzerland not fulfill warranty requests & not answer customer's respective faxes?
ProBook 4535s, keyboard 646300-BG1
1) keyboard inversion. Most character and number keys are reversed. Caps lock works reversed.
2) The cursor keys [arrow] while inside text mark the text while moving. Correct marking is impossible.
3) Dedicated arrow keys enter numbers into text or in parts of drawing when the object move over a text containing other object.
4) Two click keys operate wrongly or not at all.
5) Character keys turn into function keys, calling all sorts of menus, some of them I did not even know these exist (even in notepad ascii editor !!). Note this is not an ALT+ matter. The function keys change to something else.
6) Windows menu key not working, with some luck computer can be turned off using the touch pad only. Else using the power key the hard way.
NOTE: VENDOR HP SWITZERLAND FAILED TO PROVIDE KEYBOARD WITHIN WARRANTY PERIOD. They never answer request.
Win7.

After about 12 times trying to get the typing box display (includes closing down forum) I am finally able to see my typing on the hp-controlled screen, as hp finally diplays the textbox.
I went to the business forum. General impression is HP having a problem with keyboards for about 10 years. I could not find a single solution for any of the products mentioned there. Complaints remained unanswered.
Just to update for anyone who might be interested:
A) Cursor marks unwanted, cursor introduces numbers into t8ext. Check your pr4ose!
B) aa changes to AA and 88 changes to ((.
C) Then it gets worse: Keys change into functional, style of ALT+something. Enter windows appears which I have never seen anywhere else.
3 depth of trouble removal, open most simple editor for this:
1) press ctrl+shift, check displayed symbols in editor.
2) wipe the keyboard with your full hand, never mind the symbols shown in editor or the accoustic response of the system. Finish with ctrl+shift. Type and check displayed symbols.
3) Shut down, remove power and battery. Restart.
To not repeat trouble long term avoid spending money on HP, their service is nonexistent.
Period overview: 2007 to 2014.
